- This invention relates to dispensing apparatus for dispensing a single article at a time in sequence from a plurality of articles arranged in a front-to-back staggered stack of the type generally disclosed in U.S. Pat. No. 3,224,631, issued Dec. 21, 1965.
- this invention relates to a mechanism for dispensing a single article at a time in sequence from front-to-back staggered stacks of articles in which the releasing and dispensing mechanisms are actuated by the weight of the articles in the staggered stacks of articles and release of the releasing and dispensing mechanisms for dispensing a single article at a time from the staggered stack of articles is actuated by electrically energized means.
- this invention relates to a dispensing mechanism for dispensing in sequence and one-ata-time an article such as a single can or bottle from front-to-back staggered stacks of articles, cans or bottles, hereinafter referred to for convenience as cans, in which the weight of the cans in the stacks actuates the releasing and dispensing mechanisms.
- the mechanism is released for the dispensing of a single can at a time by electrically energized means which may be energized from any suitable source and controlled by any suitable switch mechanism, which switch mechanism may preferably be actuated by the deposit of a coin.
- this invention relates to a dispensing mechanism in which two staggered stacks of cans are arranged in front-to-back relationship with a releasing me chanism common to both stacks for releasing a can from each stack when the releasing mechanism is energized with one can then being immediately dispensed and the other can being retained until the mechanism is again energized, as by the deposit of a second coin, whereupon the other can is released and dispensed.
- articles such as cans of popular beverages are usually stored for selective sale in refrigerated cabinets with coin release mechanisms for dispensing one can at a time.
- the cans may be disposed on sloping shelves arranged one shelf above the other or the cans may be arranged in vertical staggered stacks in side-by-side bins.
- the lowermost can on each shelf may move by gravity to a position where it can be withdrawn manually by the purchaser after a coin has been deposited to release a locking mechanism allowing withdrawal on one can at a time.
- the first type of dispenser has advantages of relatively simple construction and the merchandise is visible for selection by the purchaser.
- a variety of types of beverage can be sold in this machine depending only on the number of sloping shelves provided. This multiplicity of variety is disadvantageous to the supplier who may place the machine on location since the machine can then be used for vending products other than those of the supplier.
- the practical size of the cooler, doors and the like of the apparatus limits the number of double column staggered stacks side-by-side in the cabinet.
- the number of selections are therefore limited in a machine of maximum size.
- This is advantageous to the supplier since it limits the number of beverages that can be sold other than those of the supplier.
- a further advantage is that more cans can be stored in the staggered stack type dispenser than in the shelf type machine. Even greater capacity is obtained when the staggered stacks are arranged in front-to-back relationship.
- the delivery mechanism is usually motordriven and is expensive; there is always the possibility of a mechanical jam of the mechanism in the au tomatic, positive drive of the dispensing mechanism for the cans.
- an energizing signal or current is applied to a first lock mechanism associated with the pivotably mounted latch, whereby the latch is permitted to rotate from a first, rest position to either' of a second or third position.
- the pivotably mounted latch member serves to retain the first support member in its article supporting position, while at the same time releasing the second support member to its article releasing position, whereby at least two articles from the aligned, staggered stacks thereof are released.
- One of the two released articles is dispensed for the use of the operator, while the other article is retained by an escrow bar that is held during this first cycle of operation, in its article retaining position.
- the movement of the released support member is controlled, as taught in the above-identified patent, by a non-extensible member such as a chain, whose tension is released, whereby he disengaged support member is slowly moved to its article releasing position under the weight of the stacked articles.
- the chain tensioning mechanism comprises, in the above-identified patent, a motor-driven disk to which the chain is connected. As the disk continues to rotate, the chain tension is again increased and the support member is moved from its second article releasing position back to its article supporting position and the rotatable latch member is disposed to its first, rest position, at which time the rotatably mounted latch member is again latched by the first lock mechanism.
- a de-energizing circuit switch is actuated, whereby the control circuit de-energizes the motor.
- a second cycle commences, wherein the motor-driven disk rotates through a second complete revolution.
- a second lock mechanism is actuated whereby the escrow bar is released, permitting it to be moved to its second article releasing position, and the article initially released during the first cycle but retained by the escrow bar, is now released.
- the first and second lock mechanism comprise solenoid mechanisms that are sequentially energized during the first and second cycles by the aforementioned control circuit.
- the mechanism is adapted to release articles such as cans from at least two staggered stacks thereof, corresponding cans in the adjacent stacks being substantially axially aligned of each other.
- the dispensing apparatus is adapted to vend different types of articles, such as bottles, that may be disposed in a single stack, as well as other articles such as cans, that may be stacked double from front to back.
- Such adaptation makes the dispensing apparatus more versatile and permits the refrigerated area to be used more efficiently than presentlyavailable dispensing apparatus.
- the conversion or adaptation from articles of one size to another, i.e., cans to bottles is relatively simple and may be carried out by a technician at the location of the dispensing apparatus.
- articles e.g., cans
- article dispensing apparatus comprising a reservoir or bin for receiving at least two staggered stacks of articles wherein adjacent articles in these stacks are aligned substantially axially of each other and releasable support means in the form of first and second members, one for each column of the first and second staggered stacks and movable from a first article supporting position to a second article releasing position.
- the movement of the first and second support members is controlled by a pivotably mounted latch plate, disposable from a first rest position to either of a second position wherein the first support member is maintained in its article supporting position while the second support member is released to its article releasing position or of a third position wherein the second support member is maintained in its article supporting position while the first support member is released to its article releasing position.
- a pivotably mounted latch plate disposable from either of its second or third positions, a corresponding support member is disposed to its article releasing position, thereby releasing an article from each of the staggered stacks.
- One of the two articles is dispensed while the other is retained by an escrow bar that is held during the first cycle of operation in its article support position.
- an energizing or control circuit is closed by a switch to initiate a first of two cycles of operation, for energizng a motor to rotate a coupled cam member.
- the cam member actuates a first lock means from its first rest position, wherein it engages and retains the pivotably mounted latch plate in its first, rest position to a second, unlocked position wherein the pivotably mounted latch plate is free to move to either of its second or third positions.
- the cam member continues to rotate, it engages a reciprocally mounted operating plate to move it from its first to its second position.
- the operating plate includes a surface for engaging one of the support members and as it moves toward its second position, one of the first and second support members follows its movement whereby it is disposed to its second article release position.
- the energizing circuit includes a switch actuatable by the cam upon completion of the first cycle, whereby the cam-driving motor is deenergized.
- the motor again is energized to continue to drive the cam through the second cycle of operation in which the cam engages and actuates a second lock mechanism, whereby the escrow bar is released to permit it to be disposed in its article releasing position whereby the retained article now is released.
- the cam again engages a switch whereby the motor is de-energized.
- the above-described dispensing apparatus may be readily adapted from the described mode of operation wherein relatively short articles, such as cans, are disposed in staggered, aligned stacks thereof for release in a two-cycle mode of operation, to receive a single staggered stack of relatively larger articles such as bottles.
- the reservoir or bin is modified with suitable spacers to receive the single staggered stack of bottles, the escrow bar is removed and the cam surface is adapted so that it opens the energizing circuit only at its start or initial position, thus eliminating the second cycle of operation.
- the cam is provided with first and second surfaces for operating in the first two-cycle mode of operation whereby the energizing circuit is opened twice when the first and second surfaces engage the circuit switch.
- the cam member is modified in that the second surface, e.g., a screw, is removed.

Only part of the operation of the energizing circuit shown in FIG. 13 will be explainend below, the complete operation being set out in detail in US. Pat. No. 3,486,601, issued Dec. 30, 1969 and assigned to the assignee of this invention. Briefly, power to the energizing circuit is applied across a pair of supply conductors 224 and 225 which may be connected to a conventional supply source (not shown).
- each bin 10 has associated therewith a motor 9, a switch 102, a pair of sold-out switches 212 and 213, a sold-out indicator light 214, the selector switch 215 and a selector relay 216.
- those components corresponding to a bin 10 are designated with a character followed by a letter, e.g. A, to indicate that these components operate in conjunction with the dispensing mechanism associated with the bin with the corresponding letter.
- a number of common control components are provided including coin-operated switch 217, vend relay 218, coin reject electromagnet 219, select indicator or established-credit light 220and credit release relay 221.
- vend relay 218 Upon insertion of proper coinage into the vending machine, coin-operated vend switch 217 is caused to be actuated and vend relay 218 energized. Light 220 is lit to indicate that credit has been established. Energization of vend relay 218 establishes a holding circuit for its windings through contacts 235 and 236, one more of the sold-out switches 213A to 213D and normally closed contacts 255, 256 of credit release relay 221. Also, an enabling circuit for the se- 9 lector relays is established through contacts 232 and 233 and the normally closed contacts of the vend relay. Energization of vend relay 218 also breaks the energizing circuit for the coin-reject electromagnet 219 initially maintained through contacts 234and 236.
- the dispensing apparats is now ready for a particular selection to be made by a customer, which selection is effected upon operation of a selector switch.
- selector switch 215A corresponding to column A is actuated by a customer, a circuit is established for energization of vend motor 16a and selector relay 216D.
- Selector relay 2161) is held in upon closure of its contacts 246D, 2481), while closure of its contacts 247! and 250D connect the energizing winding of credit release relay 221 in series with the winding of vend motor 16a through the now closed, but normally open contacts 265, 266 of the motor timer switch 102a.
- motor 9a which was initially energized through the selector switch 215A, is energized through conductor 242 and the holding circuit of relay 216D established with the normally open contacts 246 and 248. Operation of motor 9A drives its associated cam 26a causing the responding contact arm 104A to be actuated so as to remove power to the motor 160 from line 242. Selector relay is held in, however, by its holding circuit and the motor windings are connected in series with the energizing winding of the credit release relay through the normally open, now closed contacts 247D, 2501) of the energized selector relay 2161).
- the credit release relay When the credit release relay energizes, its contacts 255, 256 are switched to the open position breaking the vending relay holding circuit, and thus removing established credit from the machine. As the vend relay is deenergized, the holding circuit for the selector relay 2161) is in turn opened, de-energizing the selector relay. This returns contact arm 247 to its normally closed position, again completing the power circuit to the vend motor 9a through contact 251 and conductor 277, causing motor 9a to continue to drive cam 260.
- the corresponding cam member 26 and in particular its arm 98 is disposed in its initial, upright position as shown in FIG. 2.

- the latch plate 35 rotates to either its second or third position, dependent upon which of the support members 58 or 59, the lowermost can 16 rests.
- the lowermost can 16 is disposed in the second column of the staggered stack, resting upon the support arm 58.
- the weight of the can 16" in the second column forces the tumbler plate 80 downward and out of the way; as shown in FIG. 8, the
- the reciprocally mounted lock plate 78 is disposed in its first, uppermost locking position, whereby the notch 112 thereof retains the escrow bar 86 against movement, i.e., the escrow bar 86 is retained in its article support position, preventing the can 16 from being released into the tray 20.
- the cam member 26 rotates as shown in FIG. 5 from its initial position, the first contact surface in the form of the screw 94 is brought into engagement with the contact arm of the switch 102, thereby opening switch 102 and its contacts 247 and 250 (see FIG. 13) whereby the energizing signal is removed from the windings of the motor 9a.
- the first cycle of operation is completed.
- the movement of the selected support member e.g., support member 58 as shown in FIG. 8, is controlled by the reciprocally mounted plate 120 and the cam member 26.
- the roller of the member 26 engages the flange 122 and as the cam member 26 rotates, the member moves down under the weight of the column of cans bearing against the support arm 58 and therefore, against the lower flange 154 of the plate 120.
- the screw 94 engages the switch arm 104 to open the switch 102, thus completing the first cycle of operation.
- a further coin is deposited in the vending machine whereby coin-operated vend switch 217 is actuated.
- the corresponding motor e.g., motor 9a

- the first switch contact surface i.e., the screw 94, as shown in FIG. 4, is removed by simply unscrewing the screw 94.
- a coin is deposited to close the switch 217 and upon actuation of the appropriate selector switch 215A to 215D, an energizing signal is applied by the circuit of FIG. 13 to the selected motor 9.
- the motor 9 initiates the rotation of the cam member 26 to release the lock mechanism 15, whereby the pivotably mounted latch plate 35 is permitted to rotate to either of its second or third positions to release a corresponding support arm 58 or 59.
- the cam member 26 engages the topmost flange 121 of the reciprocally mounted plate 120, to guide the released support member 58 or 59 to its second. article releasing position. At this time, a single bottle 18 is released into the tray 22 as seen in FIGS. 1 and 11. Since the first contact surface or screw 94 has been removed, the cam member 26 continues to rotate until the screw 96 engages the I switch arm 104 of the switch 102, whereby the switch 102 is opened and the energizing signal applied to the selected motor 9 is removed, thus completing the operation of the modified dispensing mechanism.
- FIG. 1
- the dispensing mechanism associated with the bins 10C and 10D have been modified as more specifically described with respect to FIGS. 11 and 12 so that a single bottle 18 may be dispensed one-at-a-time.
- the dispensing apparatus of this invention may be disposed to dispense cans from at least two staggered stacks thereof in a double-cycle mode of operation, wherein two cans are first released by a support member, one of which is dispensed to the customer and upon a second energization of the mechanism as by depositing a second coin, the second can, retained by an escrow bar, is released.
- the escrow bar may be removed and the cam member modified so that it rotates through a single rotation or cycle without stopping; at the completion of the single rotation, the cam member and thus the energizing circuit is prepared to be actuated again to dispense the next .bottle.
- the conversion from the first to the second modes of article dispensing is simple in contrast to that required for the complex mechanisms of the prior art.
- the conversion contemplated by this invention may be carried out on location with simple tools in a relatively short period of time.
- a single motor has been employed with each bin or reservoir of articles, rather than dispensing articles from each bin by the use of solenoids and a common lowering device.
- the dispensing mechanism associated with one bin malfunctions, the remaining dispensing mechanisms remain operative.
- articles may continue to be dispensed from the dispensing mechanism, while a serviceman is called to repair the inoperative mechanism.
- the escrow bar as disclosed herein is cantilevered from the front, thus permitting the omission of a partition between the first and second staggered stacks of articles.
- the bins of such dispensing apparatus of this invention are easier to load.
- cam means coupled to said motor means to be rotatively driven, said cam means comprising a cam surface, and first and second switch actuating surfaces;
- first and second article support members disposed transversely across the lower end of said bin and mounted for movement from a first supporting position wherein one of said first and second article support members engages and supports the lowermost articles of the staggered stacks, to a second releasing position to permit the discharge of the articles from said bin;
- latch means pivotably mounted to be moved from a first rest position wherein said latch means engages and holds said first and second article support members in their first supporting positions when said apparatus is in a stand-by condition, to either of a second position wherein said latch means engages and holds said first article support member to prevent its downward movement to its second article releasing position, or of a third position wherein said latch means engages and holds said second article support member against movement to its second article releasing position;
- a reciprocally mounted operating plate having a surface for engaging and controlling the movement of said first and second article support members and reciprocally movable between a first position, wherein said first and second article support members are in their first position and a second position wherein a selected one of said first and second article support members is lowered with said operating plate to its second article releasing position;
- first releasable lock means for retaining said pivotably mounted latch means in its first rest position
- control means for selectively operating said motor means and including initiating means for initiating the energization of said motor means whereby said cam means is rotatively driven and said cam surface engages said first lock means disengaging it from said pivotably mounted latch means so that said latch means rotates to either of its second or third positions and said cam surface engages said operating plate directing it toward its second position whereby said one support member follows said operating plate to its second article releasing position;
- switch means disposed to be engaged by said first and second switch actuating surfaces of said cam means and responsive thereto to interrupt the energization of said motor means thus terminating the rotation of said cam means;
- an escrow bar movable from a first normal position for .retaining one of the two articles released from the stacks of articles by one of said first and second support members, to a second article releasing position; and j. a second releasable lock means engagable by said cam surface of said cam means to be disposed from a first locking position wherein said second lock means retains said escrow bar in its first normal position to a second unlocked position, wherein said second lock means releases said escrow bar and said escrow bar is disposed to its second article release position;
- said initiating means being initiated a second time for energizing said motor means and continuing the rotation of said cam means to dispose said second lock means to its second position, thus permitting the movement of said escrow bar to its second position and the release of the retained article, until said second switch surface engages said switch means to de-energize said motor means and to terminate the movement of said cam means at its starting position.
- Dispensing apparatus as claimed in claim 1 capable of being modified to receive a stack of single arti- III:
- said escrow bar is removably mounted upon said dispensing apparatus, and said cam means includes removable means bearing said first switch actuating surface so that without said first switch actuating surface, said motor means rotates said cam means from its start position through a complete rotation thereof until said second switch actuating surface engages said switch means to terminate energization of said motor means.
- Dispensing apparatus as claimed in claim 2, wherein there is included adjustable spacer means adapted to be mounted within said bin to vary the effective size of said bin, whereby a single stack of articles is arranged in a staggered manner therein.
- Dispensing apparatus as claimed in claim 1, wherein said escrow bar is suspended in a cantilevered fashion and comprise a portion extending into said bin a length not greater than the axial length of an article, whereby two stacks of the articles may be disposed in said bin without partition therebetween.
- said first releasable lock means comprises a rotatably mounted member for movement from a first locking position wherein said rotatably mounted member engages and locks said latch means, to a second unlocked position free of said latch means, and a reciprocally mounted member engagable with said cam means for movement from a first rest position toward a second position, engaging said rotatably mounted member and disposing it to its second unlocked position.
- said second releasable lock means comprises a reciprocally mounted plate comprising a notch engageable with said escrow bar when said second lock means is disposed in its first locking position for locking said escrow bar in its first article supporting position, and a cam surface for engaging said escrow bar as said second lock means is disposed from its second to its first position whereby said escrow bar is moved into said notch to be retained thereby.
- Dispensing apparatus as claimed in claim 6, wherein there is further included spring means coupled to said reciprocally mounted plate for biasing it to its first locking position.
- said escrow bar includes a cantilevered portion extending into the lower portion of said bin a length not greater than the axial length of an article, and means for suspending only one end thereof in cantilevered fashion so as to rotate between its first normal position and its second article releasing position.
- said cam means comprises a first member one end of which is rotatably driven by said motor means and its other end having a roller fixedly secured thereto forming said cam surface, and a second member for forming said first and second switch actuating surfaces.
- said first and second cam surfaces respectively comprise threaded members removably received by said second member.
